[xemacs-hg @ 2002-11-22 12:57:09 by ben] file-truename and other crash fileio.c: Fix crashes due to incorrectly ported code from FSF. realpath.c: Don't return EIO when a filename is incorrect, since the I/O error gets passed all the way up. Clean up this file and avoid using macros as a poor-man's dispatch mechanism -- it just makes it impossible to follow the code.
